Good SF ultimate goal must always be about the human condition. Literally. Always. Mary Shelley's Frankenstein arguably kick started the genre - a novel by a sex-positive teenage feminist in a corset, which tackled the question of what it means to be human, and how we connect with one another, and whether an individual can develop empathy or a moral compass in isolation, without family or society. Sf, as the genre of big ideas, and the genre that actively tackles universal questions of self, of society, of philosophy and religion and the nature of reality (yes, all of those…). It's who we are now, as well as how we might find ourselves living in the future - and that's always, always been the case. It's Margaret Atwood and Iain Banks and Arthur C Clarke and George Orwell and Octavia Butler and Robert A. Heinlein and Kurt Vonnegut and - well, all the damn classics. Hell, even “Star Trek”, cheesiest of pop culture staples, was absolutely tackling questions of civil rights and social justice on a weekly basis, under the pointy ears and sparkly moon rocks. It's always been about the characters, whether framed by technological innovation or political or geographical changes.
